Which statement about digitally signing a document is true?
A. The document is hashed and then the document is encrypted with the private key.
B. The document is hashed and then the hash is encrypted with the private key.
C. The document is encrypted and then the document is hashed with the public key
D. The document is hashed and then the document is encrypted with the public key.
A is wrong.

The signer encrypts the hash with only the private key of the signer.
The encrypted hash, which is known as the signature, is appended to the document
